Dental abnormalities in cows have seldomly been examined in research and veterinary check-up. This study estimated the prevalence of dental problems in cows. The skulls of 151 adult (> 4 years) dairy cows (Brown Swiss cattle n=81, Swiss
Fleckvieh n=70) were categorized into three age groups (AK1: 4-6 / AK2: 7-9 / AK3: 10-16 years old) and examined for the existence of 11 dental cheek teeth abnormalities, based on well-known dental pathologies in horses. The four most
prevalent dental abnormalities found were presence of abnormal spaces between 2 adjacent cheek teeth (Diastema), parodontosis, wavemouth, and food packing between cheek teeth. In 85% of all recorded skulls, 1 or more abnormalities were recorded. There were no differences in the occurrence of dental abnormalities in the
two breeds. Older animals of AK3 showed more abnormalities than younger animals, but also in the lower age categories, in average 2 abnormalities per skull were recorded. 36% of all skulls showed the presence of Diastema, which has been
described as one of the most painful oral abnormalities in horse. Dental abnormalities are prevalent in cows and probably a not recognized cause of health disorders
